Nope, I can just buy one and connect to the DC port, it has an inbuilt mppt and s up to 120w

Just 120w?

Very very poor for the price

ojesymsym:
Nothing funny about your question. It is not only valid but also achievable.

There are inverters that prioritize solar usage when there is sun, the extra power is then used to charge the batteries.

I am not sure that bros understood your question properly.

Thanks bro, Is it this inverter you mean called Grid -tie Inverter?

oweniwe:

Depends on how you look at it, if you are using it as an alternative to the grid, then yeah 120 watts is terrible.

But for me as a student and traveler, I can take it to any state, without any complex setup, the solar s are foldable and portable as well

So to me, it's basically 712wh always available as well as 120w solar to charge my fan, phone and laptop too.
Good deal to me.

Think of it like the difference between a desktop computer and a laptop computer, where this is like a laptop and the normal solar/inverter rig is a desktop.

Good morning gurus in the house,

Pls can gurus help me with quote to install a solar/inverter system in my house with the following load of 1500W.
In addition to the house load, I will also install 4 number batteries.

1) How many solar s would I need and their sizes
2) What size and type of inverter would be best for this setup
3) What size and type of Charge Controller would be best for this setup
4) What size and type of batteries would be best for this setup

Thanks as I await your responses

KINGKONG:
Dear fellow solar enthusiast and Engineers in the house……..

We all know the economy is biting harder every day and buying fuel every day to run the house while currently embarking on a house building project is really eating a big chunk on my daily expenses and I would like to take away this burden permanently by installing a solar system.

Firstly, Since I’m really new to this kind of setup… I would like to ask a lot but few questions so that I can choose or make the best decision when getting the system installed in my house. I have already settled for a 3.5KVA Inverter solar system, because I need it to power my chest freezer at home (Since this is the most important thing at home for food storage) NEPA light is non-existent in my area

1. Which inverter brand is the best based on your experience or customer reviews, I have heard about transformer based and those with microprocessors, which one is better and can withstand the test of time (I know nothing lasts forever) but I should get value for my money

2. For a 3.5KVA system, How many batteries and solar s is needed for this kind of setup to power a chest freezer for at least 4-5 hours daily

3. What is the difference between the 12V, 24V and 48V type of inverter system? Which one of this is more efficient?

4. What’s the best and efficient battery for a good solar system setup, I understand Lithium battery is good, but right now it is expensive for my budget (Cos I’m currently embarking on a project that requires more funds) Tall Tubular Battery? Gel-battery or Lead acid battery?

5. Which brand of solar s is better? I’ve read online that Monocrystalline s are the best, but which of this MC brands in Nigeria are of good quality?

6. Is it a requirement to buy lot of s with low wattage when I can get a higher wattage s with less quantity to install on the roof?

7. Why do we settle for inverters with external charge controller rather than an inbuilt charger or recommend a good hybrid inverter brand with at least 100A MPTT Charge controller

8. Lastly, is there a type of inverter that can use energy generated directly from the solar s during the day for powering of appliances while charging the battery for night use without been in use during the day time? If yes what are the setup required for this kind of system?

I know most of these questions might have been answered in previous pages, but I will be grateful if you guys can be of help to a newbie trying to get some information on solar systems

3.5kva is good. You can go for an Hybrid system, it's efficient. 3kva/24v or 5kva/48v all Hybrid inverter will serve you a long time. Batteries are the most important part of the system, so don't cheapen out on it. If you have extra money go for lithium, but if you don't quality wet Tall Tubular batteries will serve you a long time.

1) 3kva/24v with 5kwh batteries, 1500w of solar s
2) 5kva/48v with 10kwh batteries 2500w of solar s
Any of the 2 options will do.
I have used felicity hybrid, and is good. There are other brands equally good or more reliable as well. Your pocket determines your choice
We have installers on this platform, you can check out there reputation/reliability here. They can easily get the job done for you. And lastly, enjoy the free goodies from the big boss Sun

Your questions plenty ooo, The response is more like summarising a book on solar system.

If you have money go for Victron or Deye else just get a common one for your budget. MUST is ok
Number of batteries and run time depends on load. Monocrystalline is a type not a brand.
There are inverters with batteryless function which can work without batteries.

Just State your loads and budget for the system so You can get a reasonable quote.

1500W is a lot of load


1) At least 10KW of solar s

2) Not less than 10KVA or 8KW inverter

3) 200A charge controller

4) Minimum of 30KWH battery, I'll recommend lithium batteries

Just go with mctfoot's recommendations
But you will just do fine with 3.5 to 5kva inverter
Up your solar PV to about 13 or 15 kw
And if you insist on lead acid batteries you will need atleast 24 batteries assuming the loads will be on 24/7 and managing the batteries will be a lot of work and you will need to dedicate a whole room

It's when you go solar you will realize that there are more cloudy days than sunny days.

Thanks for your input, I have a washing machine, 1.5 HP Inverter air conditioning unit, Deep Freezer (I think is about 200+ liters) A small LG fridge, 65'' Inch LED TV

But out of the aforementioned appliances, I tend to do power management when the inverter is in used and also depends the last time NEPA light or generator was used to power the chest freezer..

The Chest Freezer will mostly be used on the inverter at least 3-4 hours daily depending on the cold state of the freezer...

TV is definitely gonna be in used with my starlink Internet at night.... Other items will be off... I don't even intend using my air-conditioning unit or Washing machine with the inverter, My generator or NEPA light will power these items when needed and i have a solar rechargeable fans for ventilation.

My budget for this system setup is tied to the quality of the tall tubular battery to be used, Inverter system and .... this can help me tailor my budget, hence the reason i needed some answers and recommendation to my questions to help me plan towards it

Well as suggested by someone here, a 3kva to 5kva will do, either 24v or 48v but will advise you get 48v should incase you may decide to expand later. I have been using Felicity brand. Also, on the issue of battery, it is highly recommend that you buy lithium batteries if you can. A 5kw will do for now and can be easily expanded later.

On a different note, pls how efficient is your starlink? What are the pros and cons?

Hmmmmm, I wonder why "morons" still use those items u listed up there for dedicated, highly sensitive work?

You wouldn't say this if you're a gamer.

Thanks for your input, I will go for a 24v Inverter though and Tall Tubular Batteries for now...... Na when person don build house finish i fit talk about expanding or upgrading to a new setup system.

The Starlink is very good and Ultra-fast!! I've even dismantled my DSTV dish cos i'm using IPTV and doesn't buffer a milli second... maybe except on a rainy or stormy day which doesn't last than 5 minutes

The cons:

*Monthly Sub is expensive especially when you do not stay at home all day (Though we split payment between my neighbor who uses the internet too)
* Requires steady power supply for it to work unlike our rechargeable Mifi hence more reason I wanna get a power backup plan

Hybrid inverter will fit your needs more. Many of them have the option to set solar usage and charging as priority. Meaning during the day, most of your energy needs will be from the sun during the day.

Grid tie will not fit into your use case, particularly in Nigeria. With Grid tie feeds back your excess power to the grid as a way of selling power to them. Not applicable in Nigeria to the best of my knowledge
